Refractive Surgery | Miranza - Clínica Muiños
Refractive surgery is a set of surgical procedures that modify the eye’s anatomy, especially the cornea, to definitely remove refractive defects of myopia, hyperopia, and astigmatism, so that the use of glasses or contact lenses will not be required.
How Can Visual Defects be Corrected?
The steady technological evolution has made it possible to use specific techniques for each type of refractive defect and has created a variety of options, Therefore, we do not have to limit ourselves to just one therapeutic method.
At Miranza Clínica Muiños, a study of each individual case is carried out, ruling out subclinical diseases that reject the intervention. After the study is completed, a suitable solution will be found to eliminate the dependence on glasses or contact lenses, whenever possible and based on strict safety margins.
Miranza Clínica Muiños currently carries out all techniques that are very safe and efficient to correct such defects.
The carving of the cornea can be done by directly applying laser on the corneal surface or by lifting a thin superficial layer of the cornea.
Painless and non-invasive technique. It is not done to the internal part of the eye, but to the cornea, in the outer part of the eye.
Comfortable. Out-patient process. The intervention of both eyes is done on the same day, as an out-patient process.
A quick process. The intervention only takes a few minutes.
An efficient process. Its purpose is to have visual quality identical to individuals who have never needed glasses or contact lenses.
Safe. Since 1995, over 4 million individuals have chosen this surgical technique.
Immediate recovery. The patient can carry out his/her daily tasks after a few days.
There are several techniques:
- PRK Technique: It is used directly on the corneal surface, and on fewer cases, when no other technique can be applied.
The photorefractive keratectomy (PRK) is a procedure to remodel the corneal tissue. After manually removing the epithelial tissue, this procedure uses Excimer laser, which produces a focused beam of cold ultraviolet light (UV). Each laser impulse can eliminate a small part of the corneal tissue.
PRK can be used to treat minor to moderate cases of myopia, hyperopia, and astigmatism. The re-epithelization lasts two to three days.
Lasik Technique: Currently, this is the technique that is most commonly chosen to treat myopias and hyperopias, provided the thickness of the cornea and the number of diopters will allow it.
It includes lifting the layer of the superficial stroma of the cornea. After this, the Excimer laser is applied on the resulting bed and, finally, the superficial layer is replaced, which will be held without needing stitches.
EstaThis technique will facilitate a quicker and more comfortable visual rehabilitation, since no sore will be produced in the cornea. And it also allows the correction of myopias with more diopters.
The technique includes the placement of an extremely thin and ductile lens inside the eye, and it does not remove any of its tissues. It is also a reversible procedure.
It is used to correct serious myopic or hyperopic defects.
Small implants are placed in the thickness of the cornea, which changes its curvature, and allows the correction of special defects such as keratoconus or of patients previously treated with Lasik, who have residual defects.
All interventions to correct refractive defects are carried out using topical anesthetic (eye drops), which promotes a quick functional recovery (that varies according to the technique that is applied), The patient will thus be able to progressively restart their daily activities.
Visian ICL is an implantable collamer lens that corrects eyesight. This is different from traditional contact lenses that are placed on the surface of the eye, because Visian ICL is placed inside, between the iris (the colored part of the eye) and the natural lens. After its implanted, the lens stays indefinitely in the eye. However, if your eyesight changes drastically over time, the lens can easily be replaced or removed.

Astigmatism does not allow you to see objects that are nearby or faraway, since the cornea is flattened in the upper and lower poles and the main axes have different curvature radiuses.ASTIGMATISM
